MACHINE FOR MAKING ORNAMENTAL CHA INS.

SPECIFICATION forming part of Letters Patent No. 348,850, datedSeptember '7, 1886.

Application filed June 99, 1856. Serial No. 206,662. (No model.) i

To CLZZ whom it may concern:

Be it known that 1, Jones KINDER, a subject of the German Emperor,residing at Brooklyn, Kings county, and State of New York, have inventedcertain new and useful Improvements in Machines for Making Ornamentaland other Chains, fully described in the following specification, andrepresented in the accompanying drawings, forming a part of the same.

This invention relates to that class of chainmachines particularly setforth in United States Letters Patent No. 263,533, dated August 29,1882, and embraces features of improvements thereon, which areapplicable thereto, as well as other chain-machines.

In the drawings a practical embodiment of the improvements isillustrated in connection with so much of a machine as is necessary to aclear understanding thereof, in which- Figure 1 is a side elevation ofthatportion of a chain-machine which automatically threads andinterlocks the links together provided with the present invention. Fig.2 is a plan view thereof, showing particularly the mechanism embracingthis invention divested of its supporti n g-frame and parts of theapparatus which would obscure it. Fig. 3 is a sectional elevation takenon the line :0 of Fig. 2; and Fig. 4 shows views of a piece of chainbeing formed,

the one looking at the side at right angles to that seen in the other.

The machine described in said patent is designed to produce a chainhaving the links all threaded and interlocked in one directionthat is tosay, wherein each succeeding link is threaded with the last precedinglink or links, be it a single link or a double linked chain, as the casemay be.

The present invention has for its object the production of a mechanismby which what is known as round fox-tail chain may be formed that is tosay, the formation of that class of chain wherein succeeding links arethreaded first to one side to be interlocked with one or more precedinglinks, and then to aside at right angles to the first, whereby there areproduced, practically, two interlocked series of links simultaneouslyand making one complete chain.

To this end theinvention consistsinthenovei structure and combinationsof devices too fully hereinafter described to need further preliminarydescription.

Referring to said drawings it is to be understood that the plate A willin practice support all the mechanism of the threading and interlockingportion of the machine, it being obvious that so far asthe link-formingmechanism is concerned it might be a separate apparatus, the links beingfed into a suitable guide-tube, which, on being filled, may 'betransferred to the mechanism herein illustrated in position, so that thefeedingpin'will feed a succession of links to the interlocking devices.As described in said patent, this plate A supports a table, 36, overwhich the links are fed to a vertical aperture therein, the upper edgeof which serves as a die for suitably shaping the chain as it is made,and at the same time permits said chain to pass out of the machine. Itis provided with a hollow spindle, 37, forming a continuation of saidaperture, and through which the chain passes, at the upper end of whichspindle project two needle-pointed tools, 1, that in the reciprocationsof the spindle in turn protrude through small openings in the table,slightly above the same, and withdrawn below its surface by means ofcams 40, which act upon bowls 39, secured to said spindle. These cams 40are secured to one end of a shaft, 61, (the driver-shaft in thisinstance,) that is provided with a bevelgear, (32, that meshes with alike gear, 63, at the lower end of a short vertical shaft,

18, that extends upward through the guide frame B, and is there providedwith cams (not shown) that act upon the slides 50, 51, and 44, which areeach guided in their reciprocations by suitable ways formed in saidframe B, as clearly shown in said patent. The reciprocations of thefeeding-pin carrying slide 44 in turn moves the slide 46, that carries ahorizontal needle, 7 by which the openingsin the upturned ends of a linkor links are enlarged,as well as placed in alignment to prop erlyreceive the succeeding link fed therethrough by the feeding-pin S. Theslides 51 are provided with jaws 48 49, which overlie the table 36, bywhich the links,partially bent by the primary center punch, 43, aredoubled to the extent desired, as fully set forth in said patent. Thepunch 43 is mounted vertically over the aperture in the table 36 in ahead,

42, carried at the end of avertical bar, 41, that is secured to thehollow spindle 37, and thus partakes of the reciprocations of thelatter.

In order to enable succeeding links to be threaded with preceding onesfirst at one side and then at right angles thereto, there is provided ameans by which the upturned ends of the partially doubled links arebrought in alignment with the feeding-pin 8, so that links IO will besuitably threaded with those pie viously doubled to form the twointerlocked series of linksmaking asingle complete chain. (Shown in Fig.4.) These means consist, broadly, of an oscillating block or thimble, as10, provided in the table 36, having an aperture that forms thechain-shaping die, registering with the vertical aperture in said tablefor the passage of the chain out of the machine, This block or thimbleis so mounted and arranged as to be capable of being automaticallyoscillated back and forth in about substantially ninety degrees of acircle and in properly timed concert with the reciprocations of thelink-feeding pin 8.

In practice I prefer to countersink the table 36 surrounding thevertical aperture therein, as shown, to provide a suitable seat for andthe reception of the oscillating block 10, so that its upper surfacewill be even with that 0 of the table. This seat is provided by ataper-nosed shoe, 11, firmly driven to a fixed position in said table,and bored centrally to provide a portion of the vertical aperturetherein. The under side of the block 10 will 5 of course be similarlyprovided with a taper countersunk bearing to properly fit over andreceive the nose of said shoe. The upper portion of the block will alsobe formed slightly tapering, so that a plate, as 31, forming the 40upper-surface of thetable 36 will, fitting around the tapered upperportion, confine said block and hold it to its seat, as is clearly shownin Fig. 3.

To impart the necessary oscillations to the 5 block or thimble 10, aportion of its periphery is provided with teeth that are engaged bythose of a pinion, 22, mounted at the end of a short vertical stud, 23,that is also pro-l vided at its lower end with a similar pinion, 24,engaged by a rack-bar, 25, held to duty by a bowl, 26, mounted upon astud fixed in the upper surface of the plate A, by which arrangement itwill be readily seen that if a suitable reciprocatory movement isimparted to said rack-bar it will, through said connections, impart therequired oscillations to said block. This movement may be imparted tothe rack-bar 25 in any convenient manner; but as herein shown it ispivoted to a guide-block, 27, that slides in ways out in the bed-plateA, which guide-block is connected through a link, 28, to one end of astraight 1ever, 29, the other end of which lever is,through a shortlink, 30, connected to the end of a re- 6 5 ciprocating slide, 32, thatcarries bowls 33, that are acted upon by a suitably-shaped cam, 34,mounted upon a stud, 71, depending from the under side of the bed-plate,and which is also provided with a gear-wheel, 72, that meshes with asmaller wheel, 73, fixed upon the short shaft 18. The slide 32 isslotted, as shown, to straddle and pass the stud 71, and is guided andsupported in its reciprocations by suitable ways secured to the underside of the bed-plate A. The shoe 11. will be provided with smallperforations on either side of the vertical aperture, to allow thepassage of the needle pointed tools 1, while the oscillating block 10will be provided with two sets of perforations,

as shown in Fig. 2, so that the tools 1 are permitted to risetherethrongh after each oscillating movement of said block. Thus it willbe seen, supposing the series of interlocked links a, Fig. 4, to be heldby the oscillating block 10, and that the openings in the ends of thepartially-bentlink 3 are in alignment with the link-feeding pin 8, aforward reciprocation of said pin will feed a new link therethrough,whereupon the toolslwill rise through the ends of said link to enlargethe opening at the ends, and,withdrawing the punch 43,will be caused tobear upon the center of said new link, partially bending or doubling it,and at the same time force it and thelinks composing the chain slightlydownward. through the aperture in said block, the bending-jaws 4-8 49having previousl y orsimultaneously therewith completed the doubling ofthe ends of said link 3. After this is effected and the bending-jawshave re turned or are returning to their normal position, and thefeeding-pin 8 also returning ready to feed another link, the block orthimble 10 will be oscillated or given a quarter-turn-say ll l thedirection of the arrow, Fig. et-through its connections from the cam 34,so as to present the open ends of the link 2, as seen at b, in theposition previously occupied by the end of the link 3, and in alignmentwith the link-feeding pin 8 ready to be first pierced by the horizontalstraighteningneedle 7, and afterward receive a new link, fed by said pin8, when the operations before described will be repeated, the block 10and the chain being formed being then oscillated a quarter-turn back orin the reverse direction of the arrow and the next time in the directionfirst indicated,and so on back and forth.

It is obvious that instead of one link being interlocked with the endsof one doubled link, the operations might be so timed as to cause a linkto be interlocked with the ends of two doubled links, as described inthe patent before mentioned, the result being a more closely-formedchain,without departing from this invention. It also may be observedthat the square fox-tail chain, either single or double, described insaid patent may be made on a machine provided with the improvementherein described by simply disconnecting the gears 72 73, so that nomotion is imparted to the rack-bar 25, and thence to the block 10.

\Vhat I claim is 1. In a machine for making chain, the combinati0n,witha link-feeder, as 8, of the oscillating chain-holdingb1ock,substantially as described.

2. In a machine for making chain, the combination, with the punch orbending-tool 43, of the oscillating chain-holding block, substantiallyas described.
